为了成功地在杂乱的环境中生存，回声定位蝙蝠必须控制运动行为的时间，以响应动态的感官信息。在这里，我们详细介绍了大棕蝙蝠的适应性时间控制声纳呼叫生产跟踪猎物，移动可预测或不可预测的，在不同的实验条件下。我们研究了自适应控制的声音运动的行为在自由飞行的大棕蝙蝠，棕蝠，因为他们捕获栓系和自由飞行的昆虫，在开放和杂乱的环境。我们还研究了蝙蝠的适应性声纳行为，这些蝙蝠被训练从静止位置跟踪移动目标。在每一个实验中，蝙蝠都调整了它们叫声的特征，以区分目标和杂波。在许多任务条件下，飞行蝙蝠产生了突出的声纳声音组确定为集群的回声定位脉冲与相对稳定的时间间隔，包围较长的脉冲间隔。在实验中，蝙蝠跟踪接近目标从休息的位置，蝙蝠也产生声纳声音组，这些声纳声音组的流行率增加时，运动的目标是不可预测的。我们假设，在飞行过程中产生的声纳声音组，和由蝙蝠从休息位置跟踪目标产生的声纳呼叫双峰，帮助动物解决动态目标的位置，并表示更详细的回声场景。总的来说，我们的数据揭示了自适应的时间控制声纳呼叫生产，使蝙蝠谈判一个复杂的和动态的环境。
To successfully negotiate a cluttered environment, an echolocating bat must control the timing of motor behaviors in response to dynamic sensory information. Here we detail the big brown bat's adaptive temporal control over sonar call production for tracking prey, moving predictably or unpredictably, under different experimental conditions. We studied the adaptive control of vocal-motor behaviors in free-flying big brown bats, Eptesicus fuscus, as they captured tethered and free-flying insects, in open and cluttered environments. We also studied adaptive sonar behavior in bats trained to track moving targets from a resting position. In each of these experiments, bats adjusted the features of their calls to separate target and clutter. Under many task conditions, flying bats produced prominent sonar sound groups identified as clusters of echolocation pulses with relatively stable intervals, surrounded by longer pulse intervals. In experiments where bats tracked approaching targets from a resting position, bats also produced sonar sound groups, and the prevalence of these sonar sound groups increased when motion of the target was unpredictable. We hypothesize that sonar sound groups produced during flight, and the sonar call doublets produced by a bat tracking a target from a resting position, help the animal resolve dynamic target location and represent the echo scene in greater detail. Collectively, our data reveal adaptive temporal control over sonar call production that allows the bat to negotiate a complex and dynamic environment.
